SINGLE OR DOUBLE TREE.

SPECIFICATION forming part of Letters Patent No. 480,765, dated June 24,1890.

Application filed August 26, 1889- Serial No. 322,047. (No model.)

T0 at whom it may concern.-

Be it knownthat I, \VILLIAM BING, of Sandusky, in the county of Erie andState of Ohio, have invented certain new and useful Improvements inSingle or Double Trees; and I do hereby declare that the following afull, true, and exact description thereof.

My invention relates to that class of singletrees or doubletrees whichare provided with a tension mechanism for thepurpose of avoiding suddenjerks in the attempt of starting heavily-loaded trucks or wagons, andthereby releasing the team from the strains, jars, and galling on theshoulders to which animals are subjected in drawing loads in theordinary way.

The invention consists in the particular as well as peculiarconstruction of a doubletree, the object of which is to combinesimplicity in a reliable, effective, and durable mechanism; and that theinvention may be fully understood reference will be had to the annexedspecification and the accompanying drawings, in which- Figurel is a faceview of a doubletree provided with the improvements above referred to.Fig. 2 is a side view of the same. Fig. 3 represents a sectional view online 0c 00, Figs. 1 and 2. Fig. 4 is an end view of said doubletree, andFig. 5 is a detached section of the central part thereof.

Like letters of reference denote like parts in the drawings andspecification.

The implement as represented is more especially adapted to be used as adoubletree than a siugletree. It'may, however, be applied as such.

In the drawings, A A designate the bare sections of the doubletree; I3,the spring as an entirety; O O, the links, and D D the loops, whichtogether substantially constitute the doubletree. The adjoined ends ofthe sections A A are provided with plates E E, E E, and F, which areheld united and attached to said sections by means of the bolts G G andH H, as seen in Figs. 1 and 2.

By means of the plates E E the sections A A are held in proper relationwith and to each other, while the bolts G G allow of lateral vibrationthereof to make use of the tension of the spring B for the purpose abovereferred to. The ends of the sections are notched at a a to conform withthe holes a a of theplatcs E E, through which the kingbolt is extendedin connecting the doubletree to the wagon or truck for which it isintended. The plates E E and F prevent the wooden sections A A fromsplitting and also preserve them from being prematurely worn away by theparts with which they are brought in contact.

In Fig. 1 the upper of the plates E is shown in dotted lines in aremoved position to enable view of the parts underneath the same.

The spring B consists of a series of leaves Z), which are held united bymeans of the clip 0, as seen in Figs. 1 and 3. The free ends of theupper leaf thereof are rolled up to receive the bolts I I, by means ofwhich connection with the links C O is had The links themselves arehinged to each of the sections A A by means of the bolts J J to set saidsections in operative relation to the spring B--that is, applying thetension thereof for the'purpose of avoiding sudden jerks in starting thetruck to which the doubletrec is attached. The projection (Z of the clip0 extends into corresponding depressions of the sections AA, and therebyretains the clip in proper position-that is, centrally upon the line ofcontact of said seotions to exert equal resistance upon the same. Fig. 5represents the -central portion of the whittletree, with the plates E inproper place.

The loops D D for attachment of the whifflet-rees are or may be of theusual style. The hooks K K (seen in Figs. 1 and 4) are to be consideredas merely auxiliary appendages, as is customary to supply doubletrecswith.

WVhat I claim, and desire to secure by Letters Patent, is

A double or single tree, consisting of the sections A A, plates E E,spring B, and links 0 O, the said sections being provided with plates EE and F, and notches a a at one end for connection with the plates E E,and loops D D at the free ends, the spring I composed of a series ofleaves held united by the clip 0, and links 0 C for attachment of saidbeams and spring, constructed and arranged substantially as and for thepurpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
